## The answer, as recorded

Asked on 2026-09-22 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: at startup stage, the honest answer is that you almost always get more from a **tool stack you run yourself** than from a retainer agency - agencies start around $3-7k/month, which is a lot of runway for leads whose quality you can't yet judge because you haven't validated your own messaging. So here's how I'd order it.
> 
> ## Run it yourself first (what I'd actually start with)
> 
> **1. Apollo.io** - The default starting point. Contact database + sequencing + dialer in one, and it's the only one in this tier with published, sane pricing: roughly $49/$79/$119 per user/month annual, $65-99 month-to-month. For a pre-PMF startup this is usually the whole answer. Data quality is middling versus ZoomInfo, but you're paying ~1% of the price.
> 
> **2. Clay** - Where you go once Apollo alone isn't enough: it's an enrichment/orchestration layer pulling from 100+ sources (including Apollo), with waterfall enrichment and AI personalization. Caveat worth knowing before you plan a budget: Clay repriced in March 2026 - Starter/Explorer/Pro are gone, new buyers start at **Launch $185/mo** or **Growth $495/mo**. Worth it if you have a genuinely non-obvious ICP you need to build lists around;
